Why do meteorologists are wrong so often? It's the mysterious atmospheric internal waves

Meteorologists in Utah in 2011, predicted the storms that have hit the region at the time of Thanksgiving. Schools based on their school warning declared off, leaving children at home. No scary storm but did not take place. As Julie says Crockett, a professor of mechanical engineering, it would be wrong to be angry with meteorologists, they are wrong so often. It's the atmospheric internal waves.

The atmospheric internal waves are waves that spread between layers of high and low density air. Says Julie Crockett of Brigham Young University, these waves are hard to describe, but each of them could ever experience or see. Examples would be the regular "multipass" patterns of clouds. Turbulence or aircraft. These are caused by two internal waves meet and break.

"Internal waves is difficult to capture. Spread, transmit and store energy that is around us, "says Crockett." Weather forecasts with them on a small scale count. Overall, therefore, the prediction may be slightly different than the reality. And sometimes it can be completely out of it. "

"Internal waves can affect your energy such as wind power. It can strengthen, weaken, or vice versa. This can have large-scale impacts on extreme weather events, "says Julia Crockett. He and his colleagues are trying to determine how these atmospheric internal waves work.

The atmospheric internal waves are related to internal waves, oceans formed similarly - between layers of water with low and high density. These waves are observable from space and have a major impact on the flow of water in the oceans. Both types of internal waves have in common is that they are carriers of energy, which has an effect on the climate.

Crockett in his recent research has focused on the monitoring of how to interact internal waves of large scale and small scale internal waves and what happens to the energy that the waves carry.

Under laboratory conditions, watched in a special tank propagates waves. Trying not to his students and colleagues to figure out how climate change may affect internal waves and then how these waves can influence changed the weather. "Understanding how to use wave energy spread is very important for the assessment of climate change on a large scale, "says Crockett.
